Abstract

A method of water desalination and purification includes steps of flowing salted or contaminated water concentration into a narrow or pointed portion of a corona electrode; applying an electrical potential difference between the water and an opposite electrode; generating a corona discharge in the narrow or pointed portion; evaporating the water; electrically charging water droplets and molecules formed by the evaporating step by means of the corona discharge; moving the charged droplets and molecules toward the oppositely charged electrode; condensing fresh water; and collecting fresh water. A corresponding desalination device includes a corona electrode; at least one attracting electrode; a power supply generating electrical potential difference between the corona electrode and the attracting electrode; and at least one water condensing member.
